To solve the problem, we need to identify and label the parts of a bean seed using the provided word bank. Let's analyze the diagram step by step:
Word Bank:
- Leaves
- Cotyledon
- Seed Coat
- Embryo
Diagram Analysis:
The diagram shows a cross-section of a bean seed with labeled arrows pointing to different parts. We will match these parts with the words in the word bank.
---
1. Outer Layer (Seed Coat):
- The outermost layer of the seed is the
seed coat. It protects the internal structures of the seed.
- This part is typically the largest and outermost layer in the diagram.
Label: Seed Coat
---
2. Embryo:
- The embryo is the young plant inside the seed. It consists of the radicle (root), plumule (shoot), and cotyledons.
- In the diagram, the central structure that includes the root and shoot is the embryo.
Label: Embryo
---
3. Cotyledons:
- Cotyledons are the food storage tissues in the seed. They provide nutrients for the developing embryo.
- In the diagram, the two large, leaf-like structures within the seed are the cotyledons.
Label: Cotyledon
---
4. Plumule (Leaves):
- The plumule is the part of the embryo that develops into the shoot and leaves of the plant.
- In the diagram, the small structure at the top of the embryo, which will grow into leaves, is labeled as "Leaves."
Label: Leaves
---
Final Labels:
Based on the analysis, here is how we can label the parts of the bean seed:
1.
Outer Layer (Seed Coat): Label it as
Seed Coat.
2.
Central Structure (Embryo): Label it as
Embryo.
3.
Leaf-Like Structures (Cotyledons): Label them as
Cotyledon.
4.
Small Structure at Top (Plumule/Leaves): Label it as
Leaves.

Solution:
- Top left:
Seed Coat
- Middle left:
Cotyledon
- Middle right:
Cotyledon
- Bottom:
Embryo
- Small structure at top:
Leaves
Explanation:
Each part of the bean seed has a specific function:
- The
seed coat protects the internal structures.
- The
cotyledons store food for the growing embryo.
- The
embryo contains the root (radicle) and shoot (plumule).
- The
leaves develop from the plumule as the plant grows.
This labeling helps understand the structure and function of each part of the seed.
Final Answer:
\boxed{\text{Seed Coat, Cotyledon, Cotyledon, Embryo, Leaves}}
